Justin Bieber has paid tribute to a friend who was killed in the Paris terrorist attacks.
The Sorry singer has advised his fans to "appreciate people" while they can after Universal Music Group executive Thomas Ayad was one of 89 people who lost their lives when gunmen opened fire duringan Eagles of Death Metal concert at the Bataclan theatre.
He tweeted: "Still thinking about Paris and my friend Thomas that we lost in the tragedy. He was a part of the team for years and I wish I would've had more time to thank him.
"Make sure to appreciate people while you have them. Thanks Thomas for everything you did for me. You are appreciated and missed. Thoughts and prayers are with your family & friends #PrayForParis."
Justin's tribute came shortly after The Vamps also sent their condolences to the families of Thomas Ayad and Marie Mosser, Universal Music executives who died in the attacks.
The group wrote on Facebook: "We want to pass on our deepest condolences to the families and friends of Thomas and Marie who were a huge part of The Vamps team in France and who tragically passed away Friday night in Paris. They will be sorely missed by us and all that knew them."
Following the tragedy, a number of artists, including Prince, U2 and Foo Fighters, have cancelled gigs in Europe.
